If you are moving from a Webuzo server to Webuzo then you just need to transfer the files and folders from
/home/soft/*
to the new server. You do not need to use backup and restore.
Once you move this all the installations will again be listed on the new server.

Question 3 - I backed up a wordpress site from webuzo panel. After that, assume that server crashed. So I reinstalled OS and webuzo. Then How can I restore that site?

The solution is the same but you must have downloaded the backup file in order to restore it.

Feel free to contact us if you need any further information.

The photo you were showing is just softaculous to softaculous.
How to move
softaculous to webuzo? I noticed that softaculous and webuzo are not the same db prefix names. Example. mtmocdc_wp70 and soft_wp70.
cpanel (manual install) to webuzo?
----------------

And transfer the files and folders from
/home/soft/* to the new server will copy database too?

The documentation is for Softaculous to Softaculous but moving from Softaculous to Webuzo is a similar process. The db prefix depends on the username i.e. your cpanel username is mtmocdc and the username for Webuzo is soft. This should not affect your installation.

No you will have to transfer your databases as well. In case of backups you do not have to transfer the database because the backup also contains the database and hence the database is restored on your server.
